New research from Monash University, the University of São Paulo and Deakin University has shown that a diet high in processed foods can have a negative impact on the brain’s ability to concentrate and increase the risk of developing dementia. The research announced today is Alzheimer’s disease and dementia: diagnosis, evaluation, and disease monitoringThe Alzheimer’s Society journal investigated the diet and cognitive health of more than 2,100 Australian middle-aged and older adults without dementia. The results of this study show that small increases in daily intake of ultra-processed foods (UPFs) are associated with measurable reductions in attention span, even when…

Everything around us has mass, but its origin remains one of physics’ biggest unsolved questions. According to modern theory, mass does not simply arise from matter itself. Instead, it is connected to the nature of a vacuum, not an empty space but a dynamic environment with a complex structure. Studying special particle systems can help scientists better understand this hidden framework and how mass is generated. One promising approach involves mesons, particles consisting of quarks and antiquarks bound to an atomic nucleus. This combination is known as a mesic nucleus. By studying these systems, researchers can study the structure of…

A new study reports that the constant beating of the heart may actively inhibit tumor growth in heart tissue. This is because cellular pathways in these tissues change the gene regulation of cancer cells, preventing them from multiplying. The findings shed light on the role of mechanical forces in protecting the heart from cancer and may pave the way for new cancer treatments based on mechanical stimulation. Heart cancer is extremely rare in mammals. Additionally, the adult heart has a limited ability to self-renew, with cardiomyocyte regeneration rates of approximately 1% per year. One proposed explanation for these characteristics lies…

UCLA scientists have created one of the first cell-resolution molecular maps detailing how Down syndrome affects prenatal brain development in humans. This is a resource that has the potential to resolve long-standing contradictions in the field and lay the foundation for future treatment strategies. This study scienceanalyzed more than 100,000 nuclei from human prenatal neocortical samples collected from 26 genotyped donors between 13 and 23 weeks of gestation. This period is the only period in which all the cortical neurons that a person will have for the rest of their lives are generated. This finding suggests that Down syndrome disrupts…

Gravitational waves may have played an important role in the creation of dark matter in the early moments of the universe, according to a new study conducted by Professor Joachim Kopp of Johannes Gutenberg-University Mainz (JGU) and PRISMA++ Cluster of Excellence in collaboration with Dr. Azadeh Maleknejad of Swansea University. Published in physical review letterthe study introduces new calculations that point to a previously unexplored process by which so-called stochastic gravitational waves can give rise to dark matter. This research addresses one of the biggest unanswered questions in particle physics. Everything we can see, including planets, stars, and life forms…

Americans who have abandoned their Christian faith tend to have more liberal political views than those who grew up with no religion at all. This ideological shift to the left appears to be closely related to how threatening these people perceive conservative Christian groups to be. The study was published in The Journal of Race, Ethnicity, and Politics. The demographics of the United States are changing as the number of religiously unaffiliated people grows rapidly. Demographers predict that individuals who claim no religious affiliation will become the nation’s largest population group within the next 20 years. This segment includes atheists,…

Can light rotate like a whirlwind? Researchers have shown that it is possible. Scientists from the Department of Physics at the University of Warsaw, the Military Institute of Technology, and the Pascal CNRS Institute at the University of Clermont-Auvergne have created a “light tornado” that swirls inside an extremely small structure. This advance represents a new way to build compact light sources with complex geometries, which could support simpler and more scalable photonic devices for optical communications and quantum technologies. “Our solution combines several fields of physics, from quantum mechanics to materials engineering, optics and solid-state physics,” explains research group…

Nancy Cox, a world leader in influenza research for decades, has died. Cox led the Centers for Disease Control and Prevention’s influenza team for 22 years, leading the team from a department of 14 people to a department of more than 100 people. He also served as Director of the World Health Organization’s CDC Collaborating Center for Influenza Surveillance, Epidemiology, and Control. Cox died Thursday of glioblastoma, a brain tumor. She was 77 years old. Cox, a virologist, led CDC’s efforts in seasonal influenza response and pandemic influenza preparedness. But she was at least as well known for her work…

The field has rapidly evolved over the past decade due to new evidence regarding the management of cardiovascular implantable electronic devices (CIEDs) and the rapid growth of new CIED technologies. New “2026 HRS/AHA/APHRS/EHRA/IDSA/LAHRS/PACES/STS Expert Consensus Statement Update on Cardiovascular Implantable Electronic Device Lead Management and Extraction” heart rhythmis the official journal of the Heart Rhythm Society, the Cardiac Electrophysiology Society, and the Pediatric and Congenital Electrophysiology Society, published by Elsevier, and details the latest recommendations to help clinicians and patients select the right devices and manage them over time to reduce complications and support a better quality of life. Over…

An analysis of data collected from Kaiser Permanente Hospital in Southern California between 2001 and 2014 found that children whose gestational weeks 1 to 10 and 30 to 37 coincided with periods of very high nighttime temperatures had a 13 to 15 percent higher risk of being diagnosed with autism by age 5. This paper is Total environmental science. Autism, or autism spectrum disorder (ASD), is a neurodevelopmental condition that affects how a person communicates, interacts socially, and experiences the world. This is called a “spectrum” because it can manifest in different ways and with different levels of support needs.…
